MinZ Programming Language

Modern Programming Language for Vintage & Modern Platforms

Write modern code. Deploy everywhere. From 1978 Z80 to 2025 Crystal.

🎯 What is MinZ?

MinZ is a revolutionary programming language that brings modern abstractions to vintage hardware while enabling cutting-edge development workflows. Write Ruby-style code that compiles to blazing-fast Z80 assembly or modern Crystal.

Why MinZ?

// Modern Ruby-style syntax
const NAME = "MinZ";
let greeting = "Hello from #{NAME}!";  // Ruby interpolation!

// Structs and field access
struct Point { x: u8, y: u8 }
let p = Point { x: 10, y: 20 };
let sum = p.x + p.y;

// Compile-time execution (faster than zero-cost!)
@ctie
fun distance(x: u8, y: u8) -> u8 {
    return abs(x - y);
}
let d = distance(10, 3);  // Becomes: LD A, 7 (computed at compile-time!)

Then deploy to:

• 🎮 ZX Spectrum (1982)
• 💾 Commodore 64 (1982)
• 💎 Crystal/Ruby (2025)
• 🌐 WebAssembly (Modern browsers)
• 🖥️ Native C (Any platform)

🚀 Quick Start

1. Install Dependencies

MinZ requires tree-sitter for parsing. Install it first:

# Install tree-sitter CLI
npm install -g tree-sitter-cli

# Initialize tree-sitter config (REQUIRED!)
tree-sitter init-config

2. Install MinZ

# macOS/Linux - from releases
curl -L https://github.com/oisee/minz/releases/latest/download/minz-$(uname -s)-$(uname -m).tar.gz | tar -xz
sudo mv mz /usr/local/bin/

# Or build from source (recommended)
git clone https://github.com/oisee/minz.git
cd minz/minzc
go build -o mz cmd/minzc/main.go
sudo mv mz /usr/local/bin/

# Verify
mz --version  # MinZ v0.15.4

Note: Pre-built binaries may be for a different architecture. Building from source is recommended.

3. Write Your First Program

// hello.minz
const VERSION = 15;

fun main() -> void {
    let message = "Hello from MinZ v0.#{VERSION}!";
    @print(message);
}

4. Compile & Run

# For vintage hardware (Z80)
mz hello.minz -o hello.a80

# For modern testing (Crystal)
mz hello.minz -b crystal -o hello.cr
crystal run hello.cr  # Test instantly!

📚 Code Examples

Functions and Structs

// Struct with field access
struct Point { x: u8, y: u8 }

fun distance(p1: Point, p2: Point) -> u8 {
    let dx = p2.x - p1.x;
    let dy = p2.y - p1.y;
    return dx + dy;  // Manhattan distance
}

fun main() -> void {
    let a = Point { x: 10, y: 20 };
    let b = Point { x: 30, y: 40 };
    let d = distance(a, b);
}

Arrays and Loops

fun main() -> void {
    let data: [u8; 5] = [10, 20, 30, 40, 50];

    for i in 0..5 {
        let val = data[i];
        @print("Value: #{val}");
    }
}

Ruby-Style String Interpolation

const USER = "Alice";
const SCORE = 9001;

fun show_status() -> void {
    @print("Player #{USER} scored #{SCORE} points!");
}

Compile-Time Execution (CTIE)

@ctie
fun fibonacci(n: u8) -> u8 {
    if n <= 1 { return n; }
    return fibonacci(n-1) + fibonacci(n-2);
}

let fib10 = fibonacci(10);  // Computed at compile-time!
// Generates: LD A, 55  (no runtime calculation!)

Pattern Matching (In Progress)

// Basic enum and case syntax - codegen in development
enum State { IDLE, RUNNING, STOPPED }

fun next_state(s: State) -> State {
    case s {
        State.IDLE => return State.RUNNING,
        State.RUNNING => return State.STOPPED,
        _ => return State.IDLE
    }
}

Note: Pattern matching syntax parses but code generation is still in development.

Error Propagation

enum FileError { None, NotFound, Permission }

// Function that can fail - uses @error with enum value
fun read_file?(path: u8) -> u8 ? FileError {
    if path == 0 {
        @error(FileError.NotFound);  // Proper enum syntax!
    }
    return path;
}

// Caller handles error via CY flag
fun main() -> void {
    let data: u8 = read_file?(5);
    // CY flag indicates success/failure
    // A register contains error code on failure
}

Note: @error(EnumType.Variant) resolves to a compile-time constant for optimal code generation.

Inline Assembly

fun fast_multiply(a: u8) -> u8 {
    asm {
        LD A, (a)
        SLA A        ; Multiply by 2
        SLA A        ; Multiply by 4
    }
    return a;
}

Self-Modifying Code (TRUE SMC)

@smc
fun draw_sprite(x: u8, y: u8, sprite: *u8) -> void {
    // This function rewrites its own code for 10x performance!
    // Parameters are patched directly into instructions
}

💎 Crystal Backend: Modern Development Workflow

Revolutionary Dual-Platform Development

# 1. Write MinZ with Ruby syntax
cat > game.minz << 'EOF'
const LIVES = 3;
fun game_loop() -> void {
    @print("Lives remaining: #{LIVES}");
}
EOF

# 2. Test on modern platform (Crystal/Ruby ecosystem)
mz game.minz -b crystal -o game.cr
crystal run game.cr  # Instant testing with modern tools!

# 3. Deploy to vintage hardware
mz game.minz -o game.a80  # Same code for ZX Spectrum!

Benefits:

• 🚀 10x faster development - No emulator needed for testing
• 🐛 Modern debugging - Use Crystal's debugger and profiler
• 📦 Rich ecosystem - Access Crystal/Ruby libraries during development
• ✅ Proven E2E - Crystal backend tested with complex programs
